Solar Continuum Double Stack
Esse filtro faz o que promete! Já tive um simples antes, mas esse duplo melhora ainda mais o contraste na superfície do Sol, deixando os granulos solares e as células de convecção muito mais fáceis de serem fotografadas. Meu uso é basicamente ...

ZWO 5-Position Electronic Filter Wheel for 1.25" or 31mm Filters # EFWMINI
ZWO 5 position electronic filter wheel for 1.25" filters
The EFW from ZWO is an excellent addition to an astro imaging setup for your monochrome camera. It works seemlessly with my ZWO ASI camera and capture software. AgenaAstro provides great service and fast shipping.

GSO 1.25" Color / Planetary Filter - #8 Light Yellow
Exactly What Was Needed
My older ProOptics #8 Lt. Yellow Filter developed spots & streaks. It was cheap & probably dyed-in-vat. This filter by GSO is uniform edge-to-edge, no variation regardless of angle you view through it. This bespeaks it's high-quality. ...

GSO 1.25" Color / Planetary Filter - #23A Light Red
As advertised, solid filter
I bought this solely for the occasion of the Mars opposition for viewing with my C8, and it did indeed help increase definition to the point where I was able to discern differences surface coloration. For the price especially, a good purchase.
